Embodiment Construction
[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0020] The real-time monitoring device for grounding resistance of the present invention is composed of five parts, namely: a switching power supply, a ZIGBEE system, an AC pulse constant current source, a data acquisition processing unit, and a data array unit.
[0021] Specifically: the switching power supply can process the mains power into 5V, and output 1A to power the entire system.
[0022] The ZIGBEE system can generate excitation signals, process received data signals, and display and transmit data.
[0023] The AC pulse constant current source can amplify, isolate and filter the excitation signal generated by the ZIGBEE system and output it to the data array unit.
[0024] The acquisition data processing unit can collect, filter, and reshape the voltage obtained between the voltage test electrode and the test ground pile after the signal emitted by the cur...
